If an Albuterol inhaler contains 20mg of Albuterol how many inhalation doses can be delivered if each dose contains 90mcg?

To determine how many inhalation doses can be delivered from a 20mg Albuterol inhaler with each dose containing 90mcg, first convert 20mg to micrograms: 20mg is equal to 20,000mcg. Then, divide the total amount of Albuterol by the dosage per inhalation: 20,000mcg ÷ 90mcg/dose = approximately 222.22 doses. Therefore, the inhaler can deliver about 222 doses.
